Raster Scanning for Operational Digitizing of Graphical Data

Franz Leberl, Dale Olson

Research output: Contribution to journalArticlepeer-review


The current growth of computer graphics has resulted in operational automated systems to digitize existing maps and drawings. The configuration and performance of SysScan, a general purpose hard- and software configuration for converting maps and drawings into a digital format, and to edit, store, retreive, and generally manipulate the digital data are described. A unique component of SysScan is KartoScan, a raster scanner using white light and a CCD array sensor. In the commercial mapping segment, this system has pioneered the operational application of raster scanning to a number of digitizing tasks, among them the generation of digital elevation models from contour lines, and the creation of digital polygon data sets. Experience in these applications are reported.
